What Is a Silicone O-Ring?
Silicone o-rings are used in thousands of applications, like water-proof camera housings, enclosures, automobiles, medical devices and many more. Silicone rubber is available in durometers from 10 thru 70 durometer Shore A, however, 10 durometer silicone o-rings and 20 durometer silicone o-rings are best specified for gaskets with larger cross-sections since they are easily stretched. Silicone o-rings are also called silicone seals, and custom o-rings can be referred to as molded o-rings or pre-formed o rings.
